Title: Estimating method for degree of deterioration of coating film
Inventor: KOIZUMI NOBUHIRO
IPC: G01N3/40
Filed: 1993-02-19
Abstract: PURPOSE:To enable estimation of a period of deterioration of one coating film formed under the same conditions, on the basis of a measured value of hardness of the coating film, by measuring the hardness of another coating film after a prescribed period passes after coating and also by using a specified hardness change characteristic as a reference. CONSTITUTION:A technique of measurement of a dynamic hardness wherein the hardness is measured on the basis of an indentation depth in relation to an indentation load of an indenter is used. As for a change with time of a color difference P in a usual example, for instance, almost no change is seen in a passage of one year after completion of coating. In the case of an example of hardness Q, in contrast, a change with time of the hardness Q is recognized after the hardness becomes stable through the passage of six months after the completion of coating. Herein a hardness change characteristic is determined by a prescribed numerical formula and this is used as a reference. By measuring the hardness Q of a coating film by using a microhardness meter of a low load, consequently, a period of deterioration of the coating film is determined highly precisely and easily and the degree of deterioration of the coating film can be estimated with relatively high precision on the basis of the determined period of deterioration.

Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce torque ripple and cogging torque by defining the amount of eccentricity which is a difference in a distance between the inner diameter of a stator corresponding to such a point that a gap length between a magnetic field permanent magnet and an armature is minimized, the center of the stator, and the center of the inner diameter curvature of the center of the magnetic field permanent magnet. SOLUTION: The thickness of a magnetic field permanent magnet 20 is formed so as to be the thickest at a center and get thinner gradually toward both ends. When the distance between the magnetic field permanent magnet 20 at a position where a gap length is minimized and a rotational center is Rsi, the inner side curvature of the magnetic field permanent magnet 20 is Rmi, and the offset of the inner diameter side curvature center of the magnetic field permanent magnet 20 and the rotational center is (d), the amount of eccentricity is defined as δ=d/Rsi with δ>0.09. When the value of the amount of eccentricity δ is larger than a specific point, the value of cogging torque and irregularity high volume production can be reduced. It is thus possible to reduce torque ripple and cogging torque in a four-pole, multi-winding, 22-plot, and four-brush type.
